Hi, This post is mainly for gkweb as it regards his WGA Removal tool; but anyone else that is informed is welcomed to join in of course. The WGA Validation Tool on my computer--version is 1.5.0530.0 and KB892130--is slightly different than most others, it seems. I am attaching a gif screenshot of the wga files I have on my system. I would like to completely remove the WGA from my system as it has created disaster--I downloaded Windows XP Service Pack 1 (I did not have the full service pack--only the critical updates) and upon re-boot, the computer would just NOT reboot at all--it would go into an endless loop of trying to logon, unable to log on, with error message (A problem is preventing Windows from accurately checking the license for this computer. Error code 0x800700f); and log off, than try to log on, fail, error message above, then log off, etc. I was finally able to boot in safe mode after a LONG time, and un-installed the SP1. But all of my restore points werce oddly deleted by this un-install. My copy of Win XP Home Edition is perfectly valid (OEM version Sony), with Certificate, etc. and passes the WGA Diagnostic tests and it has been confirmed by Microsoft that it IS valid. Yet, I cannot upgrade to SP1, etc. Sony tells me I have to wipe out my system and re-install everything (!) which is out of the question. Anyway, this whole issue is created by this WGA Validation Tool on my computer and I want to COMPLETELY REMOVE it. I don't want to do this the wrong way and delete some files but leave others. I am not sure that the WGA Removal tool posted by gkweb will address my version of WGA--which is why I am posting here. If u r around GKWEB, please help me out with this issue? It is most aggravating.... I do not want this WGA tool preventing me form upgrading and also "phoning" home to Microsoft everytime I boot.... An added comment is I have read that one can go into registry and set keys donotremove that have a value of 1 to 0, and it will make the WGA Tool un-installable thru Control Panel|Add/Remove Programs; but I am not sure it would just remove from the control panel list only or really remove it from system. Thanks for ur help!!!
